The headword is the perfect middle/passive participle, masculine nominative (and vocative) plural, of the verb quo/w, I fill with sweet smells; see LSJ s.v. It is perhaps extracted, and adapted, from Homer, Iliad 14.172 (web address 1), where it appears in the neuter nominative singular (tequwme/non); see the scholia there, and next note.
See also tau 240.
[1] The initial glossing participle is the same form as the headword, but from the verb qumia/w, I burn so as to produce smoke; see LSJ s.v. The second gloss is the masculine (and feminine) nominative (and vocative) plural of the two-ending adjective eu)wdh=s, -e/s; see LSJ s.v. The headword is identically glossed in Apollonius' Homeric Lexicon (150.27), the Synagoge (tau61), and Photius' Lexicon (tau112 Theodoridis). See also Lexica Segueriana 383.4 s.v. tequome/noi, and Hesychius s.v. tequwme/non and s.v. quh/eis (smoking with incense; see generally LSJ s.v.).
